A Smart Group Company
Enable seamless communication and teamwork across locations with unified communications, video conferencing, and modern collaboration platforms.
Today’s workforce is mobile, distributed, and digital-first. DEL supplies and implements collaboration solutions that keep teams connected — whether they are in the office, working from home, or on the road.
Programmes range from legacy-PBX replacement to full modern-workplace rollouts: telephony, meetings, mail and file collaboration licensed, migrated and supported from Dhaka.
